The Valiant was the basic trainer most widely used by the USAAF during WWII, representing the 2nd of the 3 stages of pilot training; primary, basic and advanced. Compared with the primary trainers in use at the time, it was considerably more complex with a more powerful engine, so faster and heavier. In addition, it required the student pilot to use two-way radio comms and to operate landing flaps and a two-position variable pitch propeller. This example is on display at the National Museum of the USAF.
